OPTOELECTRONIC DEVICE WITH AXIAL THREE-DIMENSIONAL LIGHT-EMITTING DIODES

An optoelectronic device including a matrix of axial light-emitting diodes (LEDs). Each LED includes an active layer emitting electromagnetic radiation. The matrix forms a photonic crystal having at least first and second resonant peaks in a plane containing the active layers, each first and second peak amplifying the radiation intensity at a first and second wavelength respectively. Each light emitting diode includes an elongated semiconductor element, having a first portion of a first average diameter, a second portion extending the first portion and having a cross-sectional area decreasing away from the first portion, and the active layer extending the second portion and having a second average diameter strictly less than the first average diameter, the active layers being located at the first peak locations and absent at the secondary peak locations.
